Log 01 / Jovian Dsouza

I'm an engineer who has spent the last few years shipping production systems: on-device AI for Galaxy flagships at Samsung R&D, and high-stakes backend infrastructure at CoinDCX.
My roots are in robotics: ROS navigation and manipulation, drones, a hand-built 3D printer and AI agents. Now I'm going all-in on physical AI, building robots that learn in simulation and have understanding of the real world.
I’m at my best when I can own the entire stack, hardware, firmware, models, and the software. I’ve taken this approach to winning hackathons, shipping complete products from prototype to working system.
